More @roost.tools docs site updates! We’re now serving project docs from the shiny new docs.roost.tools domain. Idk what to do with the bare domain yet, so it currently redirects to roost.tools, but projects get a nice URL like: docs.roost.tools/coop/latest More to come soon. 👀

Who else is using @roost.tools’ Osprey for moderation on ATProto? Would there be interest in some sort of shared repo for UDFs and Plugins?

The @roost.tools community site now shows contributors from the GitHub API! It doesn’t reflect every contribution to the community (e.g. folks who are active in working groups or chat but not on GitHub), but it’s a start to try to visualize who the ROOST community actually is. community.roost.tools

Screenshot of the ROOST community site. It reads “Meet us: These are the people building ROOST projects in the open.” Below the text are 80+ GitHub avatars of contributors.

Wooo, first Coop release I've directly been a part of — hoping you'll see more of that soon! I've been grinding on reducing tech debt and figuring out how to make the code more maintainable long term

We’re still refining our processes, but I think we went too long between releases! 😅 For a relatively minor update, there’s so much good stuff coming in Coop 1.1.0. And a ton from adopters using Coop in production, or first-time contributors. It’s exciting to see this community grow and develop. 😊

The community of ROOST contributors has been busy over the past several weeks working on the upcoming 1.1.0 release of Coop. We have a pre-release available for testing, and would love your feedback if you’re currently deploying Coop or are interested in trying it out.

Most tooling for fighting fraud and abuse was built for 2010s social media. The abuse evolved. The tools mostly didn't. @julietshen.online at Marketplace Risk NYC on why open source and open weight models help: you run them yourself, so sensitive data never leaves your systems. github.com/roostorg

Two of my repeated (but favorite!) conversations at TrustCon were about how other trust and safety organizations can open source some of their work, and how to _actually_ consume open source software. You hit the download button and then..? Now written up, and with slightly better artisanal visuals

Open source is new territory for trust and safety! more safety tools are being released free or open source than ever, but this is a new practice. what does it actually mean to release something as open source, and what does it take to run open source tools like Coop or Osprey for a team?
